METALLIC FABRIC.

Specification of Letters Patent.

Patented Oct. 12, 1915.

T all whom it may concern.

Be it known that I, IVILLIAM B. Ammusox, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Metallic Fabrics, ofwhich the following is a specification.

My invention relates to improvements in metallic fabrics and hasparticular reference to a novel and advantageous elastic fabric,especially well adapted for use in the construction of springmattresses, bed bottoms, and the like, in which longitudinally extendingmetal ribbons, or thin metal slats are interwoven with transverselydisposed, similar slats, which are uniformly placed, at properintervals, along the longitudinal extent thereof and secured at theirterminals to extra wide, longitudinal slats. The substantiallyflatelastic fabric thus produced is suspended in a relatively rigid frame bycoil springs attached to each end of the longitudinal members that arespaced apart at points of attachment to said frame.

One of the especial objects of my invention is to provide in a bedbottom structure, one or more transverse slats, arranged, with referenceto the longitudinal slats, so as to prevent material, relative, axial orendwise sliding movement of the longitudinal slats, and to preventspreading or relative transverse movement thereof, whereby to effect ayielding, noiseless structure, as a whole.

An important feature of my invention is the provision of longitudinalside terminal slats that are heavier and wider than the intermediateslats, and to which are riveted, or otherwise secured the ends of thetransverse slats, and to attach these wider terminal slats to the frameby means of two helical springs at each end, said springs beingseparated further at their ends that are connected to the frame. than attheir ends that are connected to the slats, whereby to more surelyreturn said terminal slats, and attached transverse slats, to theirrespective normal positions, and to provide a more substantial marginalside edge for the spring structure.

Other, further and more specific objects of my invention will becomereadily apparent to persons skilled in the art, from a consideration ofthe following description when taken in conjunction with the drawings,wherein- Figure 1 is a plan view of my spring bed bottom structure andFig. 2 is an enlarged detail of a means to prevent relative displacementof the respective members at selected points of intersection.

In both views the same reference charterminal side members 16 and 17.areeach connected to the frame end members 10 and 11, as by springs 18 and19. It will be noted that these springs have their ends relatively closetogether at the points where they are connected to the side slatmembers, and relatively far apart, as at 20 and 21, where they areconnected to the frame end members 10 and 11. Interwoven with thelongitudinal members 14 are transverse members 22 22'22". Thesetransverse members are each connected, at their terminals to the sideslat members 16 and 17, as at 23. To prevent relative longitudinalmovement of the'members 14 I prefer to slot them near their longitudinalcenter, as at-2-l, and to pass one of the transverse members 22 throughthe slots, a portion of the member 14 at the slot being displaced forthis purpose. I also slot the two transverse members 22', one on eachside of the central, transverse member 22 to prevent the lateral,relative displacement of the members 14 so that they may not move apart,to any appreciable extent, at the points of their engagement with thetransverse member 22, as when any unusual pressure is brought to bearupon any isolated area of the fabric. When this is done the side members16 and 17 will move inwardly, to some extent, against the yieldingresistance of the springs 18 and 19 but by reason of the separation ofthe springs 18 and 19, at the points of attachment to the end members 10and 11 they serve to return the displaced terminal side members 16 and17, to their original positions, when the pressureis removed, huspreserving a uniformly fiat even surface throughout the entire fabricand by the c011- stant effort and effect of the springs, 18 and 19,- tomaintain this condition, undesirable sagging 0r buckling of any area ofthe mattress support is. prevented. I prefer to thus tie thelongitudinal members together by slats, one on each side of said centralmembers by slotting the respective members but other means than thatshown may be employed for carrying out the object and intent of myinvention, whereby the longitudinal members are prevented from movingendwise, or sidewise near the central zone of the structure. 1

Having described my invention, What I claim with a view and desire tosecure by Letters Patent is:

A device of the character described comprising a resilient fabric,composed of uniformly separated, longitudinal slats and similartransverse slats interwoven together to provide a fiat surface; asupporting frame; springs connecting said longitudinal members at eachindividual end to said frame; means to prevent relative, axial movementof said longitudinal members but to permit relative transverse movementthereof at or near the longitudinal central zone of the structure, andmeans positioned atboth sides of the central zone lengthwise of thedevice to prevent transverse movement of said longitudinal members butto permit axial movement thereof.

In testimony whereof I hereunto set my hand in the presence of twosubscribing witnesses.
